Variety of Test Targets Including Among Other Types of Finds a Four-Reale and Half-Reale |
For whatever it is worth, I decided to look at the conductivity numbers for the recently found four-reale and half-reale. I forgot what numbers they produced in the field and wanted to know that so I took them out to test along with some other targets for context.
Left to right in the photo above are the targets: (1) a 13 gram four-reale, (2) a 1 gram half-reale, (3) a small very thin bit of what looks like copper found at the same site, (4) a silver cross, (5) a silver ring, (6) another silver ring, (7) a copper alloy looking piece.
I used the factory presets, except I used the Beach 1 mode, which is what I used on the beach.

Below are the conductivity numbers that I got for each item using the Equinox 600 metal detector - the same detector that found the first three and the seventh item.
Item Conductivity Reading
1. 13 gram four-reale - 29 - 31
2. 1 gram half- reale - 17
3. very small copper - 2
4. silver cross - 20-21
5. silver ring - 30-31
6. oval silver ring - 35
7. copper alloy piece - 20-21
I was most interested in knowing the numbers for the reales. The reals consistently produced numbers that were distinct from most of the other targets, except the four-reale produced numbers in the same range as one of the silver rings. The small half reale produced a very stable 17, while the numbers produced by the much larger four reale were less consistent.
I get the feeling that shape affects the conductivity number. The more thin and irregularly shaped silver cross produced numbers that were between those of the two reales. I should do a thorough experiment on that someday.
The conductivity numbers can be useful in some situations, but there is a lot of variability and overlap. It seems that the position of the object and its depth can change the numbers somewhat. And many different types of objects produce the same or overlapping numbers.
It does appear that reales will generally show conductivity numbers from around 17 and up. I do find the numbers useful to some extent even though they may not always be precise or consistent. Too much reliance on the numbers could be a big mistake.
As detectorists we are always dealing with probabilities. I would define skill as the ability to improve the probability of success through intentional action.
If there is one thing I regret not remembering from my college and professional years it is the math of probability theory and statistics. Detectorists use a variety of types of clues or signals that if properly interpreted and used can dramatically increase the probability of success. Although I don't actually need to do the math for field applications, it would be helpful for explanations

Some say heaven has streets paved with gold. I don't really know what use I'd have for that.
I see it as unpaved roads winding up and down hills sparsely decorated at various distances by two or three tightly grouped small but happy homes built by struggling young families recently returned from the war and animated by children of various ages tumbling in the summer grass and exploring every nook and cranny of the nearby woods and streams, catching frogs and snakes or sledding in the snow.
That is what I see sometimes when I awake in the private threatre of night. The gang is still there, just as it was.
In our plaid shirts and blue jeans, seven year-old David, a year older than I and a veteran at seven years of age, walks me down the road past the barns, farm fields and cows to my first day of school, neither one of us having any way of imagining what lies in the years ahead. A special good fellow, I'd like to thank David for his company in those carefree days.
He's not the only one. There was Eddie, Gary, Bobby, Loretta and Becky and others. We shared the same hills, neighbors, schools and friends for our entire childhood. We had a baseball team in summer, and a football team in the fall, even if we were a several positions short.
I'm sure I'm not the only one that awakens in the night and returns every once in a while to those green hills to meet old friends so many years and miles away.

I've been eagerly watching the surf predictions and hoping that the predicted big surf doesn't disappear.
As of this morning, it still looks good. Rather than decreasing, the predicted surf for next weekend has actually increased another foot.
Happy hunting,
